Without a priori knowledge of the upper bounds of unknown parameters , interconnections between subsystems and extemal disturbances , the stability of the closed - loop large - scale system is guaranteed by adaptive laws 该控制器不需要未知参数变化、外界扰动以及子系统互连上界的先验信息，能够通过自适应率对上述信息进行在线估计。
This robust adaptive control uses the identifier to estimate the unkonwn parameter and a " certainty - equivalence " to form a self - adaptive controlling design so as to realize the separation from identifier and controller in design 用辨识器估计系统未知参数，利用“确定性等价原则”构成自适应控制方案，从而实现了辨识器与控制器设计的完全分离。
